    Disc Rotor Rubbing 29" Fork

    So, I've had this bike for a while, and the only thing I did today was change the tires. Not a big deal, right?
    I put the wheel back on and all of a sudden, the disc rotor is scraping the fork noticeably.

    I remember some rubbing before, but I didn't remember it being this bad to align.

    Any one have any ideas? (Pics below).

    Whoa, I hadn't looked at the pics before replying

    Common prob. If you are sure the wheel is centered, re-adjust the caliper. Maybe the wheel wasn't centered originally when the caliper was adjusted.
    So the rotor is rubbing the fork leg? No rubbing prior?

    Unfortunately. It was. Demo bike and ice had it for about a month. Who knows what was done to it...

    Yup, it's centered, nothing changed. I had noticed something but not that it was killing the fork. Today, different story. All I did was remove the 9MM QR, replace tire, out back on. When I start to tighten the quick release the stanchions pull together, but that side seems to come in more/crooked. Another thing to note, on the hub, there's a knob sticking out that seems to push into the fork leg like its been ground out; instead of staying in place.

    If I have to replace the stanchions ill just move to 15/20QR since my hub is convertible. But that's a last chance solution I hope.

    Seems like you're missing an end cap or some critical piece. You shouldn't pull the stanchions together when you tighten the QR. And you have far too many threads exposed on the end of the skewer, which leads me to believe something is amiss.

    Can you take pictures of the hub off the bike?

    Hub's missing a part. That QR has way too many threads showing.

    Caution;  Merge;  Workers Ahead! Important!

    Berkley NAIL IT. You've lost the end cap for the hub, until you get it, do not even try to ride the bike like that. In case you don't know what an end cap looks like, photo is below - study the photo and then look at your hub as is, you should understand.

    Yup, missing cap. +1 for Lynx's warning and reccomendations.

    In the 1st and 2nd pic, you can see very clearly that the fork is clamped directly onto the axle that protudes from the hub. Normally there is a cap there that slides onto the axle.

    I hope the axle end and the fork dropout are OK, because those are not designed to be clamped like that. The axle end has a much smaller clamping surface than the end cap that should have been on it. Better check for damage before putting on a new end cap and riding the bike.

    Thanks guys. I believe you're right - it's missing the en cap on the disc brake side. This is the wheelset: Black Flag Expert

    I didn't even see that. I'm not even sure those were there before to be honest. Thanks for catching that.

    I hope so too, but hey might be my excuse just to convert it to a 15QR.

    As requested, up close of the disc rotor side of the hub:

    I thought it was the "non-drive side"?

    But I found these as well:
    Sun-Ringle-Dirty-Flea-Front

    I am waiting on Sun Ringle to call me back since they don't list the hub-type on their product page.
